Title: Improvements relating to the heat-treatment of metallic products for bright annealing and analogous purposes
IPC: C21D1/76
Filed: 1928-06-29
Abstract: 323,496. Sadler, A., (American Mond Nickel Co.). June 29, 1928. Drawings to Specification. Annealing; cementation.-In a process of reducing, or preventing the formation of, oxide coatings during the heat treatment of metallic goods in an electric or other furnace, a mixture of nitrogen or other inert gas and hydrogen is supplied to the heating part of the furnace and is of such low hydrogen content, viz., 2-15 per cent, and the volume of gas supplied is so predetermined that, during the deoxidation of the goods, the whole or practically the whole of the hydrogen is used up or taken out of the atmosphere. The goods after their progress through, or removal from, the heating chamber are thus cooled down in an atmosphere of nitrogen or one which contains a negligible amount of hydrogen. The goods may be passed intermittently through preheating, heating, and cooling chambers, the gas being supplied to the heating chamber in a continuous or intermittent stream. For hotrolled nickel sheets an atmosphere containing 2 per cent of hydrogen is used. Specification 132/11 is referred to.

Title: Improvements in or relating to Work Supporting Mechanism for use in Operations upon Boots or Shoes or parts thereof.
IPC: A43D71/02
Filed: 1919-07-31
Abstract: 130,616. United Shoe Machinery Corporation, (Assignees of MacKenzie, F. L.). Aug. 1, 1918, [Convention date]. Work-supports.-The invention relates to work-supports for machines having a power-operated tool, such as those used in inserting fastenings in boots &c. A mechanism is employed whereby the work-support is momentarily unlocked, pressed up by a spring to the work and then locked, prior to the application of the working clamping pressure. The locking and unlocking are operated by the starting treadle which throws the machine into operation. The device is shown applied to a fastening machine as described in Specification 9694/09. A worksupport 48, Fig. 1, pivoted at 70 to a slide 74 is unlocked by a rod 114 attached to a starting treadle 50. Springs 78 press the support upwards to the work at 6, and the support is immediately relocked to the slide 74. Further downward motion of the treadle 50 operates a rod 52 and bellcrank 54, 58, pivoted at 56 whereby the work-support is firmly pressed against the work through the operation of the lever 14, one end of which is pivoted to the support slide 12 and the other to a yielding spring slide 30. The machine is then started by a rod 66 actuated from the treadle, a fastener is inserted and then toggle means 20, 22 are broken to release the lever 14 and slide 12 so that the support is lowered for feeding the work. The locking means is shown in Fig. 2. The slide 74 is provided with rack teeth 86 which are engaged by oppositely set spring pawls 88, 90, pivoted to the housing 82 in which the part 74 slides so that neither upward nor downward relative movement is possible before unlocking. This is done by a cam plate 100 which rotates about a spindle 98 and disengages the pawls. Immediately springs 78 attached to the housing 82 and to the slide 74 at 76 press the slide and work-support up to the work. The cam 100 is moved by a ratchet wheel 104 with which there is engaged a pawl 106 pivoted at 108 to an arm 110 mounted loosely on the shaft 98, the said arm being operated by the rod 114 from the starting treadle. Upon depressing the treadle the arm 110 will move the ratchet wheel 104 until the pawl 106 engages a cam surface 116 on a plate 118 mounted on the housing so as to disengage the pawl 106 from the wheel 104 after having moved the latter a distance equal to the length of a cam surface 102 on the plate 100 thus disengaging the pawls 88, 90 and allowing them to re-engage. Further movement of the treadle does not disturb the rearranged pawls nor their connexion with the teeth on the plate 74. Specification 12262/10 also is referred to.
